OIL BURNER Filed Feb. 10, 1945 2 Sheets-Sheet l Patented Nov. 9, 1943 UNITED v STATE S PATENT OFFICE 1 Claim.

My invention relates to improvements in oil burners, the principal object in view being to provide inexpensive, efiicient equipment adapted for easy installation in fireplaces, stoves and the like, and for burning crankcase oil with safety and with maximum efficiency as regards combustion and heat generated.

Other and subordinate objects are also comprehended by my invention, all of which, together with the precise nature of my improvements, will be readily understood when the succeeding description and claim are read with reference to the drawings accompanying and forming part of this specification.

In said drawings:

Figure 1 is a view in front elevation of my improved oil burner installedv in a fireplace,

Figure 2 is a view in top plan of the improved burner,

Figure 3 is a view in longitudinal section taken on the line 33 of Figure 2, and

Figure 4 is a view in transverse section'taken on the line 4-4 of Figure 1 and drawn to an enlarged scale. 7

Referring to the drawings by numerals, the illustrated embodiment of invention has been shown as installed in a fireplace I, of the usual type, having the opening 2, formed, in part, by side walls 3 and the floor 4.

According to my invention, my improved burner comprises, as its basic. element, an elongated, trough-like oil receptacle which is' preferably formed, in greater part, of a suitable section 5 of steel, or cast iron, tubing cut down to provide a top opening 6 extending longitudinally from end to end thereof and of a suitable width. Rectangular steel, orcast iron, plates 1 are suitably secured, as by welding, not shown, to the ends of the section of tubing 5 so as to close said ends, the plates 1 being higher than the depth of said section 5 and otherwise arranged to support said section at its ends on the floor 4 in slightly elevated horizontal position. A back deflector plate 8 is suitably secured, as at 9, to the back top edge of said section 5 to extend along the rear edge of the opening 5 in upstandingposition and to curve slightly forwardly and function to deflect heat forwardly out of the fireplace I.

In the transverse center of the described receptacle is a' tubular oil feeding noozle I0 formed of a short section of tubing set into and suitably secured, as by welding II, in a central notch l2 provided in the front edge 01' said section 5, so

that said nozzle is provided with an open rear .end I3 extending part way into the receptacle,

well above the bottom thereof, and said nozzle inclines slightly from the horizontal downwardly and rearwardly to facilitate the discharge of oil;

therefrom out of said rear'end l3 into the receptacle.

An oil feed line I4 is provided beneaththe floor level to extend from a suitable gravity, or pressure, fuel oil supply tank, not shown, and which terminates in a valved riser 15 connected by an elbow [6 to a short length of-pipe l6 coupled to the front end of the nozzle l0 by a fitting l1 threaded onto and closing the front end of said nozzle.

A layer of rock wool I8 is provided in the bottom of said receptacle. The feed nozzle I0 is provided above the longitudinal center and the front half portion thereof with apertures, as at Hi, the purpose of which will presently appear.

As will be readily understood, the oil discharges from the nozzle l0 into the receptacle and is maintained, by means of the valve 20, in the riser 15, at or below the level of the layer l8 of rock wool to facilitate combustion, the layer of rock wool providing for better mixture of air with the surface oil in a manner which will be clear. The apertures 19 provide for air entering-the nozzle I0 above the oil therein so as to prevent gas from forming in the nozzle l0 and explosion of such gas in said nozzle, it being understood that the level of the oil in the nozzle I0 is kept below the apertures l9.

The described burner provides suflicient equipment for burning crankcase oil heretofore, for the most part,.wasted, and which, because it is generally disposed of as waste, is available at a very low cost. Thus, by virtue of my invention, heating equipment is rendered available at a low cost, and what is usually a waste product is advantageously utilized. However, my improved equipment has the added advantage of being well adapted to burning fuel oil or a mixture of fuel oil and waste oil.

The foregoing will, it is believed, suflice to impart a clear understanding of my invention without further explanation.

Manifestly, the invention, as described, is susceptible of modification without departing from the inventive concept, and right is herein reserved to such modifications as fall within the scope of the appended claim.

What I claim is:

In an oil burner, a trough-like oil receptacle comprising a section of tubing having the upper part thereof cut away to form a top opening therein extending from end to end of the section, a pair of flat rectangular plates fixed to the ends of the section' to close the same and extending below the bottom of the section to support the section in elevated position, a gravity feed oil nozzle of tubular form fixed to one edge of the opening in the transverse center of the section and inclining downwardly into said opening, a

valved oil supply line connected to one end of the,

nozzle-and a heat deflecting plate extending along the other edge of the opening and curving upwardly from said last edge.
